Q & A / SUNN Mustang date query.

« Last post by Steve Cook on March 02, 2025, 09:05:38 am »

A good few years ago I posted about my own Indi made Mustang indicating it had a date of 1976 stamped on the neck heel (it certainly looks like it at least!). I was informed that that wasn't possible as production in India wasn't licensed by Fender until the early 80's (no research since has proved otherwise), yet the fact remains. It's a cream-white HSS strat', gold foil logo with Made in India stated and weighs a ton - if anybody can shed any light on why the neck heel displays Aug. 1 76 I'd be extremely grateful ... it doesn't appear to be an afterthought as it's covered with lacquer.
Brief history - I've owned it for around 15 or so years, it cost the grand total of ?25 at the time ($31 / ?30) and has since had a fret level and recrown, and a steel tremolo added (a vast improvement to the tone / sustain). The humbucker tone control doesn't appear to be functioning as I think it should, so a rewire and possible upgrade to a 4 wire pup is on the cards, with a 500K push-pull control replacing the original. I might also swap out the 250K volume for a 500K one, for a more balanced approach.

Q & A / Re: Hooking up Sunn Concert Controller 1 to a Cabinet

Yes, the 16 ohm cab should be fine.

Yes, it matters how many cabinets you hook up to it. If the 215 is a 4 ohm cabinet, then no other cabs should be used along with it. If it's an 8 ohm cabinet, then another 8 ohm cabinet could be used, for a total of 4 ohms.

How are you planning to use it?

It should work into 16 Ohms, just not as loud as it could be.

Q & A / Hooking up Sunn Concert Controller 1 to a Cabinet

« Last post by Ganoderma lucidum on February 26, 2025, 04:11:14 am »

Hi,

I recently acquired a Sunn Concert Controller 1 and I wanted to make sure I hook it up correctly. The only set of speakers that I have to hook it up to right now is a 300 watt Peavey 4x12 cabinet which is 16 ohms. Would this work at all? If not, I'll wait to hook it up to something more appropriate.

The back of the Controller says that the ohms should be no lower than four ohms or the amp could overheat and shut off. Would it depend on how many cabinets/speakers you are running the amp into? I plan on eventually getting whatever kind of speakers it would be appropriate to use this.

Thanks for any advice on using this correctly.

Q & A / Re: Recently Repaired 1968 Blowing Fuses... What to do?

250W 3V is not a fuse rating I'm familiar with. 250V 3A would make sense, but would not be the correct fuse for this amp.

I find myself wondering if you have the correct fuse. It should be a 2A slo-blo fuse. A regular fast-blo fuse of 2 or even 3 amps would blow immediately.

The amp should not be turned on with the wrong fuse installed. The purpose of the fuse is not to protect the amp, the purpose of the fuse is to prevent the amp from catching on fire and burning your house down. The amp needs to be looked at by someone who can address whatever is causing the fuse to blow.

Was just wondering - I see the schematic that aligns with what I have has 250W 3V fuses. Looks like the tech replaced the fuse.
Amp itself says 2A though. I see the amp has a new 2A fuse in it.

Anybody aware of the context surrounding this? I see it for example discussed online in places like this. https://www.reddit.com/r/GuitarAmps/comments/xy4xak/sunn_solarus_fuseschematic_says_3a_amp_labeled_2a/

Just wondering if I should try replacing with 3A fuses first.
